If you have or know someone with access to a dispensary, I'd look into some hash oil infused gummy bears. I don't smoke herb like I used to so my tolerance is pretty low, but 120 mg THC gummies had me so lit I was reevaluating my whole life. I was actually looking forward to the dose wearing off cause it was that strong. Then again my buddy has a monster THC tolerance and that dose of gummies didn't touch him.
Basically what I'm saying is the gummy bears seem to really soak up the active THC and for me have worked very well, almost too well. Be safe and have a good birthday.
